Abstract (en)

[origin: WO2014019893A1] The invention relates to a method and equipment for manufacturing a hollow glass article having a specific inner glass distribution, wherein the method for manufacturing the hollow glass article includes the following steps: inserting a blank (38) of the article into a finishing mold (26); and forming the article in said finishing mold (26) by injecting at least one gas, which is at a forming pressure, inside the blank (38) of the article. During the forming of the article in the finishing mold (26), at least one gas injection point (54A) is moved in order to direct the gas toward at least one predetermined area of the blank (38), the gas being injected at least at a finishing pressure in order to achieve a specific inner glass distribution of the article.
